Europe’s historically unstable political terrain has enjoyed three generations of stability and peace as part of Pax Americana. But with the weakening of classic Atlanticism, both external pressures and internal instabilities have returned to the Old World. The election of Donald Trump as President of the United States has made the vulnerabilities of Europe – and those of America – most visible also to those who chose to ignore them. On the eve of the Trump presidency, the Richard C. Holbrooke Forum assesses the changes in Europe’s strategic landscape and look at the challenges to statecraft and diplomacy in a new era. A panel discussion entitled “Post-Atlantic Europe? Diplomacy and Statecraft under President Trump,” with Jan Techau, director of the Forum; Vali Nasr, dean of the School of Advanced International Studies (SAIS) at Johns Hopkins University; Thomas Bagger, head of policy planning at the German Federal Foreign Office; moderated by Alison Smale, Berlin bureau chief of the New York Times, with welcoming words by author and journalist Kati Marton.
